FIELD OF THE INVENTION

Generally, the disclosure relates to electronic devices. More specifically, the disclosure relates to methods, systems and devices for creating a content capture session executable by a plurality of electronic devices.

BACKGROUND

There are several situations where content needs to be captured using two or more content capturing devices. For example, in film production, it is common to use a multiple camera setup for capturing visual content of a scene. The multiple camera setup includes two or more cameras positioned at different spatial coordinates. Accordingly, the scene may be recorded from two or more different viewpoints. Such multi-camera systems often require a substantial level of technical expertise, director supervision, and a significant amount of post-production editing.

For example, in order to produce a final composition of content captured using the two or more content capturing devices, complex post-production editing is generally required. Videos obtained from the two or more cameras in the multiple camera setup may be subjected to synchronization and stitching under supervision of a human editor. As a result, a final video including visual content captured from different viewpoints may be obtained. This process of stitching is complex, time consuming and burdensome. Moreover, processing content captured using two or more content capturing devices involves the use of complex processing tools. For example, postproduction editing of the videos obtained from the multiple camera setup require complex and expensive video processing software.

Accordingly, there is a need for improved methods, systems and devices for capturing content using two or more content capturing devices.

I. Platform Overview

This overview is provided to introduce a selection of concepts in a simplified form that are further described below. This overview is not intended to identify key features or essential features of the claimed subject matter. Nor is this overview intended to be used to limit the claimed subject matter's scope. The methods, systems and devices for managing a content capture session executable by a plurality of electronic devices may be used by individuals or companies to manage content capture sessions executable by each of a master electronic device and one or more client electronic devices.

The present disclosure relates to techniques for managing content capture sessions. Managing the content capture session may include one or more of defining the content capture session, creating the content capture session, modifying the content capturing session, monitoring the content capture session and terminating the content capture session. The disclosed techniques may be used for collaboratively capturing content using a plurality of electronic devices. Further, the plurality of electronic devices may be configured for capturing content in one or more forms such as, for example, audio, images, video and multimedia.

One of the plurality of electronic devices may function as a master electronic device while one or more other electronic devices may function as one or more client electronic devices. Further, a content capture session may include participation of the one or more client electronic devices under the direction of the master electronic device. In other words, the master electronic device may be configured to manage the content capture session. Accordingly, the one or more client electronic devices may be configured to communicate with the master electronic device. Further, the one or more client electronic devices may be configured to participate in the content capture session under the control of the master electronic device.

The master electronic device may be operated by a user called as a “director”. Further, a client electronic device of the one or more client electronic devices may be operated by a user called as a “camera person”. Accordingly, the director may be enabled to provide control inputs in order to manage the one or more content capture sessions. As a result, greater control is provided to the director in managing the content capture session.

Further, the control inputs may include one or more session parameters corresponding to a content capture session. The one or more session parameters in general may represent information that characterizes one or more aspects of the content capture session. For instance, the one or more session parameters may determine which electronic devices of the plurality of electronic devices may participate in the content capture session. Similarly, the one or more session parameters may determine how the plurality of electronic devices may participate in the content capture session. Likewise, the one or more session parameters may determine conditions under which the plurality of electronic devices may participate in the one or more content capture sessions. Further, the one or more session parameters may determine how content captured by the plurality of electronic devices may be processed.

Further, in some embodiments, the one or more session parameters may represent information regarding one or more operations to be performed in relation to capturing content. The one or more operations may be performable at various time instants in relation capturing content. For instance, in some embodiments, the one or more operations may be performable prior to initiating capture of content. In some embodiments, the one or more operations may be performable during capture of content. In some other embodiments, the one or more operations may be performable subsequent to termination of capture of content.

Accordingly, techniques of the present disclosure may be used for collaboratively capturing content such as, for example, video, using multiple content capturing devices such as, for example, smart phones. For instance, a scene including one or more physical objects may be synchronously captured using two or more video cameras. Accordingly, depending on spatial positions of the two or more video cameras, different views of the scene may be captured synchronously.

Initially, an app executable on the master electronic device may present a graphical user interface (GUI) to the director in order to activate recording using multiple devices. Once activated, the director may be presented with an option to select one or more other users to act as camera persons. For example, the director may be enabled to select one or more friends who are in the vicinity of the director. This may be accomplished, for example, by discovering presence of client cameras over a Bluetooth network.

Further, the director may be enabled to send an invitation to the selected users to act as camera persons. The invitation may be sent over a communication network such as Bluetooth, Wi-Fi, etc. In some instances, the invitation may include a personal note from the director describing the purpose of the invitation, time of recording, place of recording, subject of recording and any other specific instructions to be followed by the camera persons while recording video such as a camera angle to be adopted.

Upon receiving the invitation, a user may either accept or reject the invitation. Subsequently, acceptance or rejection of the invitation corresponding to the one or more selected users may be displayed to the director. This allows the director to know who among the one or more selected users would be collaborating in recording the video.

Subsequently, the client cameras may be temporally synchronized with the master camera. For instance, a current time on the master camera may be transmitted to all the client cameras. Accordingly, the client cameras may change their current times to the current time on the master camera. Thus, both the master camera and each client camera may be synchronized in time. Additionally, the director may be able to indicate one or more session parameters corresponding to the collaborative content capture specific to the device operated by each of the camera persons. The one or more session parameters may include information such as camera settings to be used during the collaborative content capture, post processing to be performed on the captured videos and storage/transmission related operations related to the captured videos.

Thereafter, the director may be enabled to issue commands to the client cameras in order to coordinate recording of the collaborative video. For instance, the director may be enabled to initiate recording at a time T.sub.i by activating a record button on the GUI. Consequently, each client camera may begin recording of video at T.sub.i according to the one or more session parameters. At any point in time, the director may be enabled to issue further commands such as for example, a command to pause the recording of video. Accordingly, each client camera may receive the command and pause recording. Similarly, the director may be enabled to issue a command to terminate recording of video at the client cameras.

Subsequently, the client cameras may send the respective video recordings to the master camera over a communication network such as Bluetooth or Wi-Fi. Alternatively, the video recordings from the client cameras may be transferred to the cloud from where the director may access the video recordings. Thereafter, the director may be presented with a synchronized display of all the video recordings in a split screen. Thus, the director may be able to view an event from multiple different views as synchronously captured by respective client cameras.

Both the foregoing overview and the following detailed description provide examples and are explanatory only. Accordingly, the foregoing overview and the following detailed description should not be considered to be restrictive. Further, features or variations may be provided in addition to those set forth herein. For example, embodiments may be directed to various feature combinations and sub-combinations described in the detailed description.

II. Platform Configuration

FIG. 1 illustrates one possible operating environment through which a platform consistent with embodiments of the present disclosure may be provided. The operating environment may comprise methods, systems, and devices collectively referred to as a platform. The platform may include a master electronic device and a client electronic device. The platform may further include computing devices in operative communication with the master electronic device and the client electronic device. Moreover, the platform may include a networking environment for facilitating communication between the master electronic device, client electronic device, and various computing devices. Although the present disclosure refers to various functions and operations performed by particular components of the platform (e.g., a master electronic device or client electronic devices), it should be understood that some platform components may be interchanged with others, and/or, where necessary, combined with other components to perform the functions and operations intended.

By way of non-limiting example, a collaborative content capturing platform 100 may be interconnected using a network 110. In some embodiments, network 110 may comprise a Local Area Network (LAN), a Bluetooth network, a Wi-Fi network and a cellular communication network. In other embodiments the collaborative content capturing platform may be hosted on a centralized server, such as, for example, a cloud computing service. A user 105 (e.g., director) may access platform 100 through a software application. The software application may be embodied as, for example, but not be limited to, a website, a web application, a desktop application, and a mobile application compatible with a computing device 1300. One possible embodiment of the software application may be provided by the camera app included on electronic devices such as smart phones and tablet computers.

As will be detailed with reference to FIG. 1 below, the computing device through which the platform may be accessed may comprise, but not be limited to, for example, a desktop computer, laptop, a tablet, or mobile telecommunications device. Though the present disclosure is written with reference to a mobile telecommunications device, it should be understood that any computing device may be employed to provide the various embodiments disclosed herein.

The computing device 1300 may be configured to communicate with each of client devices 1-3 over the network 110. Further, the computing device 1300 may be configured to provide a user interface to the user 105. Accordingly, the user 105 may interact with the computing device in order to manage a content capture session executable by one or more of the client devices 1-3. For example, the computing device 1300 may display a GUI to the user 105 in order to provide one or more session parameters for managing the content capture session. For instance, the one or more session parameters may indicate a selection of one or more of the client devices 1-3 to participate in a collaborative capture of content. As another instance, the one or more session parameters may indicate device settings for the client devices 1-3 to be used while capturing content. Accordingly, the one or more session parameters provided by the user 105 may then be transmitted to the client devices 1-3 over network 110.

Further, the GUI may enable the user 105 to enter commands corresponding to controlling capture of content such as for example, initiation of content capture, pausation of content capture and termination of content capture. Accordingly, a command entered by the user 105 may then be transmitted to the client devices 1-3 over network 110. Upon receiving the command, the client devices 1-3 may perform a content capturing operation dictated by one or more of the command and the one or more session parameters. Subsequently, the content captured by the client devices 1-3 may be transferred to the computing device 1300 over network 110. As a result, the user 105 may be able to consume the content recorded collaboratively in accordance with the one or more session parameters.

III. Platform Operation

Further, an electronic device of the two or more electronic devices may include a content capturing means configured to capture content.

In general, the content may include a representation of one or more physical characteristics. For example, in some embodiments, the content may include visual content. Accordingly, the content may be a representation of optical characteristics such as, but not limited to, reflectance, transmittance, luminance and radiance. For instance, visual content corresponding to a scene may include electronic representation, such as, for example, a digital representation, of reflectance of visible light from one or more objects in the scene as captured from two or more viewpoints. Accordingly, the two or more electronic devices may be positioned at different spatial coordinates corresponding to the two or more viewpoints. Examples of content may include one or more of, but not limited to, image, video and audio. In various embodiments, the content may correspond to, but without limitation, one or more sensory modalities. The one or more sensory modalities may include visual modality, auditory modality, tactile modality, olfactory modality and gustatory modality.

In order to capture the content, the content capturing means may include one or more sensors configured for sensing one or more physical characteristics corresponding to the content. For example, the content capture means may include an image capturing device configured for sensing electromagnetic radiation in a scene and generating a corresponding electronic representation. Further, the image capturing device may be configured for sensing electromagnetic radiation corresponding to one or more wavelength bands. As an example, the image capturing device may be a video camera configured for sensing electromagnetic radiation in the visible spectrum. As another example, the image capturing device may be configured for sensing electromagnetic radiation in the infrared spectrum. In another embodiment, the content capturing means may include a microphone configured for sensing sound waves and generating a corresponding electronic representation such as, for example, a digital representation.

Accordingly, subsequent to receiving the master-mode indicator, the client electronic device 202 may operate as the master electronic device 200.

Further, the two or more electronic devices may include each of the master electronic device 200 and the one or more client electronic devices 202. Accordingly, the master electronic device 200 may include content capturing means configured to capture content. In another embodiment, the two or more electronic devices may include two or more client electronic devices. Further, the master electronic device 200 may be configured to control capture of content using the two or more client electronic devices.

The master electronic device 200 may include a user interface module 204 configured to receive indication of one or more session parameters. In general, the user interface module 204 may be any means configured to receive input from one or more users.

In another embodiment, the user interface module 204 may include an input device such as, but not limited to, a keyboard, a mouse, a touch-pad, a stylus, a digital pen, a voice recognition device, a gesture recognition device and a gaze detection device. In some embodiments, the user interface module 204 may be implemented using one or more of hardware and software. Examples of hardware include, but are not limited to, sensors and processors. Accordingly, in various embodiments, the indication of the one or more session parameters may include one or more of a touch on a GUI, a depression of a key, a mouse click on a GUI element, a gesture, a voice command and a gaze corresponding to the one or more session parameters.

In general, the one or more session parameters may represent any information that may be used to control a state of one or more of the master electronic device 200 and the one or more client electronic devices 202. In some embodiments, the one or more session parameters may represent any information that may control one or more of the master electronic device 200 and the one or more client electronic devices 202 in relation to capturing content. Further, in some embodiments, the one or more session parameters may represent information that characterizes one or more aspects of the content capture session. For instance, the one or more session parameters may represent information about which operation is to be performed, conditions under which the operation is to be performed and how the operation is to be performed. As an example, the one or more session parameters may represent information that may be used to enable or disable a functionality of one or more of the master electronic device 200 and the one or more client electronic devices 202. As another example, the one or more session parameters may represent information that may be used to trigger one or more of the master electronic device 200 and the one or more client electronic devices 202 to perform one or more operations.

In some embodiments, the one or more session parameters may include one or more device indicators. Further, the one or more client electronic devices 202 may be configured to participate in the content capture session based on the one or more device indicators. Accordingly, in some embodiments, the one or more device indicators may indicate one or more of the client electronic devices 202 that may participate in the content capture session. For instance, the one or more device indicators may include one or more device identifiers such as, for example, Electronic Serial Number (ESN), International Mobile Equipment Identity (IMEI) number, a network address, Internet Protocol (IP) address, Media Access Control (MAC) address, Bluetooth identity and Service Set Identifier (SSID). In another instance, the one or more device indicators may include one or more user identifiers corresponding to users of the one or more client electronic devices 202. Examples of user identifiers may include one or more of, but not limited to, first name, second name, middle name, pseudonym, nick-name, guest name and a contact such as a telephone number or an email address. Further, in some embodiments, a mapping of the one or more user identifiers to the one or more device identifiers may be maintained at one or more of the master electronic device 200, a server communicatively coupled to the master electronic device 200 and the one or more client electronic devices 202. Accordingly, the one or more device identifiers may be determined based on the one or more user identifiers.

Further, in some embodiments, a device indicator may be used for indicating which client electronic device of the one or more client electronic devices 202 may function as the master electronic device 200. For instance, each of the one or more client electronic devices 202 may receive a master-mode indicator along with the device indicator. Accordingly, the client electronic device corresponding to the device indicator may function as the master electronic device 200.

In some embodiments, the one or more session parameters may include one or more operation indicators. Further, the one or more client electronic devices 202 may be configured to perform one or more operations based on the one or more operation indicators. Similarly, in some embodiments, the master electronic device 200 may be configured to perform the one or more operations based on the one or more operation indicators. The one or more operations may be performable at various time instants in relation to capturing content. For instance, in some embodiments, the one or more operations may be performable prior to initiating capture of content. In some embodiments, the one or more operations may be performable during capture of content. In some other embodiments, the one or more operations may be performable subsequent to termination of capture of content.

In some embodiments, the master electronic device 200 may synchronize with the client electronic device 202 using a sync process as illustrated in FIG. 11. The master electronic device 200 is represented as “Device 1” while the client electronic device 202 is represented as “Device 2”. At step 1102, the sync process may begin. Accordingly, at step 1104, Device 1 may transmit its current time value represented as Current_1 D1 time to Device 2. Subsequently, Device 2 may receive and transmit the Current_1 D1 time back to Device 1 at step 1106. Thereafter, at step 1108, Device 1 may calculate a sendTime based on a difference between Current_1 D1 time and Current_2 D1 time, where Current_2 D1 time may be time of reception of Current_1 D1 time from Device 2. Subsequently, at step 1110, Device 1 may transmit a (Current_3 D1 time+sendTime) to Device 2, where Current_3 D1 time is a current time later than Current_2 D1 time measured at Device 1. Thereafter, at step 1112, Device 2 may be configured to calculate a deltaTime based on difference between Current D2 time and (Current_3 D1 time+sendTime). Subsequently, at step 1114, a forecast D1 time may be calculated based on (Current_2 D2 time-deltaTime+sendTime). Further, at step 1116, the forecast D1 time may be transmitted to the Device 1. Subsequently, at step 1118, an allowable time error between Device 1 and Device 2 may be calculated based on (current_4 D1 time-forecast D1 time). Thereafter, at step 1120, the allowable time error is compared to a predetermined tolerance value represented as timeDiff. If the allowable time error is less than timeDiff, the process proceeds to step 1112 where the sync process is determined to be successful. However, if the allowable time error is greater than timeDiff, the process proceeds to step 1124 where the sync process is restarted again beginning from step 1102.

Furthermore, in various embodiments, based on the time value, each of the master electronic device 200 and the one or more client electronic devices 202 may be configured to capture content synchronously.
